[Xen-devel] Adding Xen to the kbuild bot?

[Andy Lutomirski <luto@xxxxxxxxxx>]

Hi all-

Would it make sense to add some basic Xen PV testing to the kbuild bot?

qemu can boot Xen like this:

qemu-system-x86_64 -kernel path/to/xen-4.5.2 -initrd 'path/to/bzImage
kernelarg otherkernelarg=value" -append 'xenarg other_xen_arg'

This should work with any kernel image for x86 or x86_64 with CONFIG_XEN=y.

Linux has never been been able to do virtio under Xen, which will
screw up your scripts, but I'm cautiously optimistic that virtio will
work as expected on a Xen guest starting with Linux 4.6.  If you want
to play around, it should work in this tree:

https://git.kernel.org/cgit/linux/kernel/git/luto/linux.git/log/?h=virtio_dma

I'm hoping to get that queued up for real in the next couple of days.

--Andy
